TEMPERATURE-CONTROLLING APPARATUS.

Application filed March 29, 1928.

This invention relates to apparatus for co ntrollin 3; the temperatures in buildings and other closed structures, one of the objects being to provide a forced circulation of air over elements which can be utilized either for ljieatiug or cooling the air, said elements being maintained at the desired temperature by simple and e'l'l'icient means provided for that purpose.

A further object is to provide apparatus of this character which can also be utilized, on a small scale, as a hair dryer in establishments where a number of customers are served at the same time.

A further object is to provide apparatus of this character which is sinuqle, compact, and cilicient and can be operated at low cost.

ll ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed may be made within the scope of what claimed, without departing llOlll the spirit of the invent-ion.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a vertical longitudinal section through the apparatus set up for use as a house heater. the nested spiral coils being shown in section.

lihrure 2 is a section on line E2-2, Figure 1.

Figure 3 is a section on line 3-3, Figure 1.

Referring to the figures by characters oi rei erei'ice 1 designates a drum having; heads 2 in which are seated the ends of air tubes 3. One end of the drum communicates with a fresh air conduit 4: opening; directly into the tubes and, in the structure illustrated housing an electric fan 5 which, when operated, will force air through the tubes. The other end of the drum 1 is seated in a header 6 from which are extended outlet pipes 7 going to diil'erent points where the air is to be utilized. Water pipes 8 and 9 open into the drum adjacent the heads 2 and are provided with valves 10 whereby the supply of water is cut oil under certain conditions.

Adjacent the drum there is provided a heater asing 11 in the bottom of which is located a gas burner 12 or other heating means. Above this heater and within the casing 11 are nested spirally celled pipes 13,

all of the coiled pipes being connected at their lower ends by pipes 1 1 to a leg 15 extending downwardly from the drum near one end. Another shorter leg 16 is extended downwardly from the other end portion of the drum and is connected by pipes 17 to the upper ends of the coiled pipes.

When it is desired to use the apparatus for heating fresh air the valves 10 are closed and fuel is ignited at the burner 12. A circulation of water will thus be set up through the spiral coils 13 and the drum 1 so that heat will be transmitted by conduction through the Walls of the tubes 3 to the streams of air flowing through the tubes from conduit 4 to header 6. This circulation will be continuous as long as the heater is in operation and the flow of air will be insured. by the operation oil the fan. The tempered air leaving the header 6 through the pipes 7 can be used for heating rooms or other iuelosures and, as before explained, can also be used for drying purposes.

tiring warm weather the use of the burner or heater 12 can be discontinued and the valves 10 opened. Thus a circulation of cold water from any suitable source can be established through the drum with the result that the air passing through the tubes 3 will be chilled and. thus can be utilized for cooling purposes.

Under some conditions the air tubes 3 and the drum 1 can be placed in an inclined or a vertical position so that a rapid circulation fan thus be established without utilizing a ran.

What is claimed is:

Apparatus of the class described including a. (lllllll, air tubes extending; therethrough, a iresh air conductor opening into the tubes at one end, air distributing; means communieating with the tubes at the other end, a spirally coiled pipe, a long and a short leg; depending from the drum and communicating respectively with the bottom and top of the coiled pipe, means-tor heating the coiled pipe, said pipe and its connections with the drum constituting means for setting up a circulation of a heating medium within the drum and around the tubes, and means for effecting a forced circulation of air tl'n'ough the tubes, said tubes constituting means for heating the air.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.

DEE TUCKER.
